Title:
  Kernel log floods filesystem when capturing from Alsa USB device on
  USB3 port (NEC Corporation uPD720200 USB 3.0 Host Controller)

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  When starting alsa capture, the kernel log gets completely flooded (ex: gst-launch alsasrc device=hw:1 ! fakesink) with the following messages:
  [  384.872349] cannot submit datapipe for urb 0, error -22: internal error

  Tested kernels are 2.6.32-37-generic-pae up to 2.6.32-41-generic-pae. Here's dmesg when plugging the device for the first time:
  [   45.804249] usb 3-4: new full speed USB device using xhci_hcd and address 0

  when typing sudo lsusb -v, similar messages appear:

  [  126.945033] xhci_hcd 0000:03:00.0: WARN: short transfer on control ep

  [  126.962020] xhci_hcd 0000:03:00.0: WARN: Stalled endpoint

  Please note that this audio chipset is widely used on mid-range audio
  devices (Alesis products, MXL, Sure, Behringer, etc...) so that's not
  a very isolated case.
